減速機技術資料：

減速機參數(shù)，到底哪些參數(shù)需要知道呢？這里將詳細的說明。決定減速機中熱功率的校核的是什么？是周圍環(huán)境的溫度。這是我們需要分析的一個數(shù)據(jù)，作為減速機，它的內(nèi)部應該有一個電機，這個電機的級數(shù)究竟是多少，合適不合適，它的功率又是什么，也需要我們來做深入的分析，此外，減速機的安全系數(shù)如何，大家的安全性可不可以得到可靠保證，更是重中之重，決不可忽視。還有就是減速機在什么設備上來使用，以及使用它可能的一些結果，也是絕對不可以馬虎的事項。減速機輸出軸的徑向力和軸向力的校核，也是需要注意的一點。 電機功率N=1.15*m*g*v1.2/1000*效率，轉速N=60*v*i/3.14*d          根據(jù)功率、轉速選擇電 電動機的功率．應根據(jù)生產(chǎn)機械所需要的功率來選擇，而減速機則是根據(jù)所要傳遞的功率或者扭矩，以及工作所需要的轉速來選擇的。
電動機的功率．應根據(jù)生產(chǎn)機械所需要的功率來選擇，盡 
量使電動機在額定負載下運行。選擇時應注意以下兩點： 
(1＞如果電動機功率選得過小．就會出現(xiàn)“小馬拉大車”現(xiàn) 
象，造成電動機長期過載．使其絕緣因發(fā)熱而損壞．甚至電動 
機被燒毀。 
(2)如果電動機功率選得過大．就會出現(xiàn)“大馬拉小車”現(xiàn) 
象．其輸出機械功率不能得到充分利用，功率因數(shù)和效率都不 
高(見表)，不但對用戶和電網(wǎng)不利。而且還會造成電能浪 
費。 
要正確選擇電動機的功率，必須經(jīng)過以下計算或比較： 
(1)對于恒定負載連續(xù)工作方式，如果知道負載的功率 
(即生產(chǎn)機械軸上的功率)Pl(kw)．可按下式計算所需電動機 
的功率P(kw)： 
P=P1/n1n2 
式中 n1為生產(chǎn)機械的效率；n2為電動機的效率。即傳動效 
率。 
按上式求出的功率，不一定與產(chǎn)品功率相同。因此．所選 
電動機的額定功率應等于或稍大于計算所得的功率。
